It means that they would have met at some point Hence, we extend both rays behind the lens We see that the rays form an image behind the lens (on the left side). So, the image is virtual And image formed would be larger than the object We can say that Image is virtual (behind th...

11.4.2 Models for Microscope Image Formation Most microscopes can be assumed to be shift invariant linear systems with a position-independent psf, where point sources located anywhere in the sample create psfs of constant shape at the detector. In its simplest form, then, the formula for microsc...
(Fig.2d). Growth for several cell cycles results in the multi-cellular chains ofB. subtilisand microcolony formation, providing a dataset with increasing cell density and a large number of cell-to-cell contacts. When we tested different networks for this challenging dataset, we found that U-...
Then, as shown in FIG. 3, an etching mask126for forming the inner lens108is formed on the passivation layer/inner lens formation film107′ by photolithography. Thereafter, as shown in FIG. 4, the etching mask126is heated and reflowed to form a convex lens having substantially the same sha...
Phase mask optimization refers to the models where we simulate image formation through the opt-conv layer consisting of a 4f system with a phase mask in the Fourier plane. Here the tensor to optimize is the height profile of the phase mask, from which the system PSF is computed. The height...

This invention provides an optical lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power; a second lens element with positive ref
In the image-formation optical system according to the invention, it is also possible to impart power to at least one rotationally asymmetric surface having the aforesaid reflecting action by decentering it with respect to the axial chief ray. With this arrangement, it is possible to make correcti...
